Wilson pleaded guilty in April to misdemeanor campaign finance fraud for improperly steering $8,000 to the state Democratic Party while he was an insurance company president. He was Missouri's governor for three months after the death of Gov. Mel Carnahan.

A St. Louis law firm donated $5,000 to the state Democratic Party but hid the cost in legal bills submitted to the insurance company when Wilson was in charge. Wilson used his own money to hide an additional $3,000 donation from the law firm.
